VALVE.

Specification of Letters Patent.

Application filed January 3, 1911.

To all whom it may concern:

Be it known that I, JOHN J. MEYER, a citizen of the United States, and a resident of Yonkers, in the county of Testchester and State of New York, have invented a new and Improved Valve, of which the following is a full, clear, and exact description.

The invention relates to that type of valves used in liushing tanks and similarv devices and commonly known as ball cocks.

The object of the invention is to provide a new and improved valve of this type for use with high or low pressure water supply, and arranged to insure long life of the valve, to prolong the period of repairing or rewashering the valve, and to prevent waste of water by leakage.

For the purpose mentioned use is made of a valve disk for engagement with a valve seat, and means for moving the said valve disk toward and from the said seat, and simultaneously turning the valve disk with a view to present a different surface for contact with the valve seat at each operation. Use is also made of a seat plate removably arranged in the valve body between the inlet and outlet thereof, the seat plate being provided with displaceable valve seats.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional side elevation of the valve arranged as a ioat-controlled supply valve for the top of a flushing tank; Fig. 2 is a cross section of the same on the line 2 2 of Fig. l; Fig. 3 is a similar view of the same on the line 3 3 of Fig. l; and Fig. 4 is a sectional side elevation of a modilied form of the valve arranged as a float-controlled supply valve for the bottom of the flushing tank.

The valve body A of the valve illustrated in Fig. l is preferably made of two sections A and A2, of which A is an inlet section and A2 is an outlet section, the sections being preferably screwed together as shownin the said Fig. 1. The section A is provided with a bracket A3, screwed or otherwise secured to the top of the flushing tank B on which the valve is shown applied. In the inlet section A is screwed or otherwise removably held a transversely-extending seat plate or diaphragm C provided with a number of tapped holes C', one, two or more of which are en- Patented July 18, 1911;

gaged by a valve seat D, while the remaining tapped holes C are closed by screw plugs E, as will be readily understood by reference to Fig. l. By the arrangement described one or more seats D may be used at a time according to the amount of liquid intended to pass from the inlet section A to the outlet section A2, in a given time.

The valve seat- D is adapted to be closed or opened in the outlet section A2 by a valve F having a washer or face F of rubber, leather or other suitable material, fastened in place by a retaining ring F2, and the said valve F is provided with a stem F3 mounted to turn and to slide in the direction of its axis in a bearing A4 formingpart of the section A2. The outer end of the valve stem F3 is provided with recesses FL arranged in a circle, the lower one of which is adapted to be engaged by the head G of a lever G fulcrumed at G2 on the bracket A5, forming part of the section A2. The lever G is preferably ioat-controlled so that when the water rises in the flushing tank B to a predetermined level then the lever G is swung upward so that the bead G pushes the stem F3 to move the valve F into a closed position relative to the valve seat D.

In order to rotate the valve F on moving it bodily toward the seat D, the following arrangement is made: On the lever G is fulcrumed a pawl I-I pressed on by a spring I-I to hold the free end of the pawl in engagement with a ratchet wheel I having its stem I secured centrally to the outer end of the stem F3. Thus when the float-controlled lever G swings upward to move the valve F toward the seat D then the ,pawl H rotates the ratchet wheel I and consequently the valve F so that by each upward swinging movement of the lever G the valve F is turned to present a different surface for .contact with the valve seat D. The lever G is preferably provided with a terminal head G engaging a semispherical recess F4, so that in case the pawl I-I and ratchet wheel I do not suliiciently turn the valve F for the ball G to exactly register with an aperture F4 at the next upward swinging movement of the lever G, then the said ball G in moving into engagement with the recess sufficiently turns the valve F to cause the pawl II to properly engage the corresponding tooth on the ratchet wheel I. Thus the action of the head G on the stem F8 is such as to insure at all times proper engagement of the pawl H with the ratchet wheel I. On the downward or return swinging motion of the lever G the'head G engages the back ot the ratchet wheel I and thus the valve F is moved outward into open position to allow the water to flow through the seat D into the tank B.

From the foregoing it will be seen that by the arrangement described any number ot valve seats D may be used on the seat plate C, and the valve F presents a diterent surface to the valve seat D at each operation, thus insuring long life of the valve, at the same time preventing leakage at the valve seat D and the contacting portion of the tace F of the valve F.

As shown in Fig. et, the valve body J is made in two sections J J2, of which the inlet section J is provided with a thimble J 3 extending through the bottom of the flushing tank B and secured thereto in the usual manner, the lower end of the thimble J3 being coupled to the wat-er supply pipe K. In the section J is arranged a seat plate K having a valve seat K and plugs K2 similar to the seat plate C, the seat D and the plugs E, and the said valve seat K is adapted to be engaged by a valve L having its stem L mounted to slide and to turn in the bearing J t arranged on the section J 2 of the valve body J. The outer end of the valve stem L is provided with a reduced portion forming spaced toothed surfaces L2, L3 adapted to be engaged by teeth ll, N2 formed on the lever N fulcrumed at N3 on a bracket J5 extending from the bearing J4. The lever N is pivotally connected atI its free end by a link O with a lever P fulcrumed on a bracket J G extending from the bearing J4, and the said lever P carries the tioat rod Q of a float rising and falling with the water in the flushing tank B. When the float rises a swinging motion is given to the lever P' so that the levei` N is swung downward, thereby engaging its tooth N with the toothed surface L2 and pushing the valve L downward in engagement with the seat K', at the same'time turning the stem L by the action of the engaged teeth N and L2. When the flushing tank B is emptied of its contents the tioat sinks and in doing so a reverse swinging movement is given to the levers P and N so that the tooth N 2 moves in contact with the toothed surface L3 to lift the valve L and at the same time to turn the same so that the valve seat K is open and water can flow into the tank B. By the arrangement described the valve L is bodily moved toward and from its seat, and at the same time an intermittent rotary motion is given to the valve L to present different contacting surfaces to the seat K at each operation with a view to prevent leakage and insure long life to the valve.

On top of the stem L is formed or secured a spray plate Li to detiect any water that may pass through the bearing J".

lt is understood that the seat plate (j or K can be readily removed on taking the sections ot' the valve body apart, so that the valve seat can be changed or repaired, it necessary.

Instead of using a single disk or washer F, use may be made of a plurality of such washers, each fastened in place by a screw or other 1n lans.

lt is understood that various mechanical devices can be used for imparting bodily movement to the valve F (or L) toward ol' from its seat plate C (or K), and turning or rocking the said valve simultaneously, and hence I do not limit myseltI to the detail construction shown and described as the same may be varied without deviating trom my invention.

Having thus described my invent-ion, l claim as new and desire to secure by Letters Patent.:
